EFI LIVE DTC Emission codesUpdated 2 years ago
DTC codes may appear once the delete tunes have been installed, and the cause of the issue can be due to an incorrect installation or other factors.
Our first solution would be to re-flash the tune file. Sometimes, the initial flash may not take in all the data, and re-flashing the tunes can resolve the issue. If this does not work, we recommend clearing the code and checking for any vacuum leaks in your air intake system, such as the intake manifold or air intake filter.
Additionally, unplugging the Air Intake Throttle Valve, located on your intake's elbow, can also resolve the issue. We also suggest checking to ensure all sensors related to the emission systems are unplugged, as they could be interfering with the delete tune.
If the AITV was not unplugged, unplug it , and flash the tunes again. If there are still some sensors related to the emission system still in tact.. please unplug and re-flash the tunes.
If you have already done all of that, send us the following information via our support form
- Year/Make/Model

- Transmission type (68RFE, AISIN, G56, ALLISON)
- Transfer case type: manual or SOTF

- AutoCal serial number (located on the back of the device)
Please note that it may take 1-2 business days to hear back from our techs, but we assure you that we will do our best to resolve your issue in a timely manner.
